Answer:
6
Step-by-step explanation:
Chords within a circle are proportional. Proportional means that they form equal ratios. To solve for y, set up a proportion.
The ratios we will create will be 
where each long and short form an angle.
So write:
To solve, cross multiply numerator with denominator.
12(4) = 8(y)
48=8y
6=y
200 * 2/15 = the number of students that didn't read any books. This is 26.6, so 40 is not a good estimate 40 students is 20 percent versus 26 being approximately 13 percent.
hope this helps i tryed
ur welcome(;
have a great day
Answer:
F, I only
Step-by-step explanation:
We can see this is a quadratic equation and c is the constant. What changes when we change the constant? It will change the h intercept which we can see is also known as a y intercept (the y axis is renamed as h).
You can also use graphs to visualize this, try changing the constant in the equation and you can see the y intercept change.
so the answer is F, I only.
